Ketanji Brown Jackson's appointment means white men are not in the majority on the US' highest court for the first time in 233 years.
Joe Biden, who has a speech impediment, slipped up while trying to complete his one-word definition of America, instead delivering an incomprehensible word salad.
Jackson, 51, was appointed to the federal bench in 2013, and was backed by three Republican senators last year when she was elevated to the DC Circuit Court of Appeals, seen as a staging ground for aspiring Supreme Court justices.
